Some of you know my little drill press, just a cheap small standard one, but it has a history of a friend extending the column another friend sending me a adjustment screw and me making table, dust control and more for it, so I will like to keep it alive if possible.Here it is.It is…......blue.And if you look careful you might see that I use a clamp for power switch…Not really good.This is the switch.It has a relay inside.Zoom….Here info on the machine.

So what is the problem or question MaFe!

First of all the company stopped selling parts for it and my switch are dead… That’s a problem.

Then I ordered some switches on E-bay, but when they arrived I found out they were only switches, no relay…

From the brief description, I don’t even know what your problem is for sure.

Now, is the problem just that the switch will not latch? Is that why you need a clamp to hold the switch closed?

Obviously a European drill press, are you running 240V, 3 phase? I think that is the standard across the pond. If so, then I suspect the switch just connects 2 phases to the relay coil and that the relay contacts then switch all three phases ON to the motor. Do you have any wiring diagrams for this unit?

Hi Mads. Here is what I see from the plate on the drill press and the schematic from Guede:it is 230 volt motor. It looks like the blau 4 wire and the braun 8 wires are both hot wires which go directly to the motor.

You would need just a double pole single throw 10 amp switch that would make and break the two hot wires and the ground would be always connected( shown as the ground hooked to #11). The schematic shown must be all that is inside your switch. That switch you bought should be able to be hooked to the Blau4 and the Braun 8 wires that go to the motor and it is a 7 amp switch so it will handle 350 watts okay. Being that you got the switch from the UK, I would think it is a double pole single throw 230 V switch.

Have you tested it with a VOM meter to see if you push the ON button, that the contacts stay connected?

...................Good luck my friend. I wish you lived down the street. I’d walk over and test it out for you…...................Jim

The Switch.Its a NVR No Volts ReleaseHow it works is:-a. If there is a power failure i.e. black out the relay will release and drop the power path to the machine.This is a safety feature to prevent uncontrolled start upon the power being restored.b. Upon a person physically pressing the green start button the switch operates a relay the relay closes and applies power to the drill.No matter how many times the switch is pushed is is redundant.

To power off the drill either push the Red button or drop the powerAny switch willdo its just that if you turn on the switch andd then plug it in (for whaterver reason the tool will start)

NVR no voltage no switchNormal switch, can be switched on regardless of power

Hi all,Thanks for all the answers.I will try to take a Picture of the inside, but has not had time to go to the shop.Think I will just give it a go with the switches I bought.So I just have to figure out the wirering, here the diagram will come in handy, thanks.(I tried to look my self on the web for a diagram or manual, but coud not find it – lol).Thanks again,Mads

So tested the action and found out it worked just as two parallel switches.So I could simply replace it with the other type wire by wire.Simple and easy!And since I know now the relay is not a must, I will feel comfortable, thanks.
